Hi all,
Wondering if anyone can clarify.
I have two harmonic balancers, one from an 850 and the other from a 998 A+ (998 is replacing the 850)
With the dual belt (which ive never come across before) will I run i to clearance issues with the radiator mounts if going into a standard 850?
Or, just bolt on the old 850 balancer and be done with it?

The dual pulley was for a pollution air pump on a Clubman. Just use the single and avoid the problem entirely if you like.

There is only one solution here, use the dual pulley to drive a supercharger.

They aren't Harmonic Balancers they are just engine pulleys.

I believe that a duel water pump pulley was used for the air pump on Leyland Minis (Clubmans) not the engine pulley.

Thanks for the replies everyone. Standard 850 pulley it is.

Check for cracks around the rivets.

Clubby and late Moke 998s had a cast iron pulley not sheet metal. Stronger.

Looks to be ok and usable.
If anyone has a later cast one that will fit without issues, feel free to get in contact with me.
